  Abstract

In this letter, a new orthogonal FTN (Faster-Than-Nyquist) signaling based on a Cholesky precoder is proposed. When using a SRRC transmit filter with a roll-off factor α, the orthogonal FTN guarantees the orthogonality between all transmitted symbols with a condition of that a symbol period is larger than the 1/(1+α) times of the Nyquist rate. Due to this orthogonal property, the proposed FTN perfectly resolves the problems of higher decoding complexity and performance loss imposed in the conventional FTN.
